Full title and description

ISO 13936-2:2004 — Textiles — Determination of the slippage resistance of yarns at a seam in woven fabrics — Part 2: Fixed load method. This part of ISO 13936 specifies a laboratory method for measuring the resistance of yarn systems in woven fabrics to slippage at a sewn seam using a fixed-load test procedure.

Abstract

ISO 13936-2:2004 describes the fixed‑load method for determining seam slippage (movement of warp or weft yarns at a sewn seam) and is intended for apparel and upholstery woven fabrics, including stretch fabrics that contain elastomeric yarns. The method is not intended for certain industrial fabrics such as beltings. The standard defines sampling, specimen preparation, apparatus, conditioning, test procedure, calculation of results and reporting.

Scope

This part of ISO 13936 specifies a test method to determine the resistance offered by the yarn system of a woven fabric to relative movement (slippage) of yarns at a sewn seam when a defined load is applied. It applies to woven apparel and upholstery fabrics and to stretch woven fabrics (including those with elastomeric yarn); it excludes many industrial textile products (for example beltings). The procedure covers specimen cutting/patterns, stitch and sewing requirements, conditioning, the fixed‑load test itself and result reporting.

Key topics and requirements

• Principle: a folded seamed specimen is cut and loaded perpendicular to the seam under a fixed load; the resulting seam opening (millimetres of yarn displacement) is measured and reported.
• Applicability: designed for apparel and upholstery woven fabrics and most stretch woven fabrics; not suitable for many industrial fabrics (e.g., beltings).
• Specimen preparation: defined specimen dimensions and cutting patterns (examples and annex patterns provided); directionality tested for warp and weft; avoidance of selvedges and non‑representative areas.
• Sewing requirements: use of a controlled stitch type and sewing conditions (commonly single‑needle lockstitch), stitch placement and margin specified to ensure repeatability.
• Apparatus: constant‑rate‑of‑extension (CRE) tensile tester or suitable loading device, appropriate grips/clamps for tear testing, and force‑measuring system with defined accuracy and data acquisition capability.
• Conditioning and pretreatment: specimens conditioned in the standard textile atmosphere (ISO 139); agreed pretreatments (laundering, dry‑cleaning) can be applied and reported.
• Test procedure and parameters: fixed load applied (as specified for the fabric class), hold/load time and the method for measuring seam opening are prescribed; results usually reported as seam opening at the specified load or as the mean of replicate specimens.
• Reporting: test report to include specimen orientation, stitch/thread details, loading conditions, conditioning/pretreatment, numeric results and number of replicates.

Typical use and users

Used for quality control, comparative testing, product development and specification verification in the textile and apparel supply chain. Typical users include textile testing laboratories, garment and upholstery manufacturers, R&D teams, quality assurance departments and standards bodies that need repeatable, comparable data on seam performance.

Related standards

ISO 13936 is a multi‑part series; related standards include ISO 13936-1:2004 (Fixed seam opening method) and ISO 13936-3:2005 (Needle clamp method). Other related textile test standards often referenced alongside seam‑slippage tests include ISO 13935 (seam tensile properties) and tensile/strength standards such as ISO 13934. These complementary standards cover alternative test principles, seam rupture behavior and general fabric tensile properties.

FAQ

Q: What is this standard?

A: ISO 13936-2:2004 is the ISO laboratory test method titled "Textiles — Determination of the slippage resistance of yarns at a seam in woven fabrics — Part 2: Fixed load method," which measures seam slippage under a prescribed fixed load.

Q: What does it cover?

A: It covers specimen selection and cutting, sewing and stitch requirements, apparatus and conditioning, the fixed‑load test procedure (applying a constant load and measuring seam opening), calculation of results and report content; applicable to most apparel and upholstery woven fabrics and many stretch woven fabrics.

Q: Who typically uses it?

A: Textile testing laboratories, garment and upholstery manufacturers, product developers, quality assurance teams and standards organizations use it for QC, materials comparison and product specification.

Q: Is it current or superseded?

A: The 2004 edition (Edition 1) is the published ISO document for Part 2. ISO documents are subject to periodic systematic review; users should confirm the current status with their national standards body or ISO catalog for any amendments or replacements.

Q: Is it part of a series?

A: Yes — ISO 13936 is a multipart series: Part 1 (fixed seam opening method), Part 2 (fixed load method — this document) and Part 3 (needle clamp method). The parts provide alternative procedures to assess seam slippage under different test principles.

Q: What are the key keywords?

A: seam slippage, slippage resistance, fixed load method, woven fabrics, seam opening, textile testing, ISO 13936.
